In the US, higher education in the life sciences is being overhauled. There is now a move both to change the way we teach biology students, emphasizing more engaging approaches, and to clearly define what it is a student should know. And for advanced degrees, there is a push to prepare students for a range of possible career paths, not just the tenure track. Cyrus Martin reports.

This paper explores life insurance holdings from a general equilibrium perspective. Drawing on the data explored in Chambers, Schlagenhauf, and Young (2003), we calibrate an overlapping generations lifecycle economy with incomplete asset markets to match facts regarding the uncertainty of income and demographics. We then estimate that life insurance holdings for the purpose of smoothing family ...

LED system life is one of the least understood parameters, especially in application environments. As a result, any lifetime claim for a complete LED...

Ever since John Conway introduced the game of Life in 1970 [2], amateur and professional mathematicians have been obsessed by finding new complicated structures, and finding new applications for the seemingly chaotic behavior of Life forms. Perhaps its addictive nature stems from the simplistic rules: each cell on a square lattice is either on (alive) or off (dead). The Moore neighborhood of a ...

In this paper, the effect of interference fit on fatigue life of holed plate of mechanical joints was investigated experimentally. Fatigue tests were carried out on the holed specimens of Al-alloy 7075-T6 alloy. The interference fit process consists of force fitting a fastener into the hole with a negative clearance (diameter of the fastener is larger than of the hole) that produces beneficial ...
